First he was in The Man in the Iron Mask. In that film, he played Raoul, Athos' son. Athos was played by John Malkovich. And Peter Sarsgaard managed to be creepier than Athos! At the time, setting Mr. Sarsgaard up against Leonardo DiCaprio as an alternative for the young lady was laughable. Laughable. It still is. Even though Mr. DiCaprio had seriously gross hair in the movie.
Next, we come to K-19: The Widowmaker. That was a terrible movie. Its one redeeming feature was that Mr. Sarsgaard's character dies of radiation poisoning. I think he had a girlfriend, and she was probably sad. But no matter--he was still appallingly off-putting, even before he started oozing and sweating.
One must admit that Mr. Sarsgaard's irritating weirdness went virtually unnoticed in Garden State. Because that movie is full of people you know, and you hate them. At least he only robbed corpses. That was much less gross and infuriating than stupid Natalie Portman.
He's not that good-looking. I don't think he's a particularly good actor, because I think his characters are supposed to be vaguely appealing, and they are not. So what's the deal, people? Can't we just send him and Maggie Gyllenhaal to some weird island where they can be mildly sinister together?
